Interpreting
Functions
Cluster: Understand the concept of a function and use
function notation.
Common Core
Interpreting Functions F-IF
1. Understand that a function from one
set (called the domain) to another
set (called the range) assigns to each
element of the domain exactly one
element of the range. If f is a function
and x is an element of its domain,
then f(x) denotes the output of f
corresponding to the input x. The
graph of f is the graph of the
equation y = f(x).
2. Use function notation, evaluate
functions for inputs in their domains, and
interpret statements that use function
notation in terms of a context.
3. Recognize that sequences are
functions, sometimes defined
recursively, whose domain is a subset of
the integers. For example, the Fibonacci
sequence is defined recursively by f(0) =
f(1) = 1, f(n+1) = f(n) + f(n-1) for n ≥ 1.

Interpreting Functions F-IF
4. For a function that models a
relationship between two quantities,
interpret key features of graphs and
tables in terms of the quantities, and
sketch graphs showing key features given
a verbal description of the relationship.
Key features include: intercepts; intervals
where the function is increasing,
decreasing, positive, or negative; relative
maximums and minimums; symmetries;
end behavior; and periodicity.★
5. Relate the domain of a function to its
graph and, where applicable, to the
quantitative relationship it describes. For
example, if the function h(n) gives the
number of person-hours it takes to
assemble n engines in a factory, then the
positive integers would be an
appropriate domain for the function.★
6. Calculate and interpret the average
rate of change of a function (presented
symbolically or as a table) over a

between two quantities.

Building Functions F-BF
1. Write a function that describes a
relationship between two
quantities.★
a. Determine an explicit expression, a
recursive process, or steps for calculation
from a context.
b. Combine standard function types
using arithmetic operations. For
example, build a function that models
the temperature of a cooling body by
adding a constant function to a decaying
exponential, and relate these functions
to the model.
c. (+) Compose functions. For example, if
T(y) is the temperature in the
atmosphere as a function of height, and
h(t) is the height of a weather balloon as
a function of time, then T(h(t)) is the
temperature at the location of the
weather balloon as a function of time.

3. Identify the effect on the graph of
replacing f(x) by f(x) + k, k f(x), f(kx), and
f(x + k) for specific values of k (both
positive and negative); find the value of k
given the graphs. Experiment with cases
and illustrate an explanation of the
effects on the graph using technology.
Include recognizing even and odd
functions from their graphs and algebraic
expressions for them.
4. Find inverse functions.
a. Solve an equation of the form f(x) = c
for a simple function f that has an
inverse and write an expression for
the inverse. For example, f(x) =2 x3 or
f(x) = (x+1)/(x-1) for x ≠ 1.
b. (+) Verify by composition that one
function is the inverse of another.
c. (+) Read values of an inverse function
from a graph or a table, given that the
